#4923: FPU context init/switch not working well on more than 2 tasks on Cortex- Mx/ARMv7-M platform ----------------------+--------------------- Reporter: kgardas | Owner: (none) Type: defect | Status: new Priority: normal | Milestone: Component: arch/arm | Version: Severity: major | Resolution: Keywords: | Blocked By: Blocking: | ----------------------+---------------------
Comment (by Sebastian Huber): We were able to reproduce the issue. It is a problem in the FPU context save/restore during interrupt processing. Under certain conditions, the FPU context is restored from an uninitialized frame which could enable the flush-to-zero configuration. I am currently quite busy. I will add it to my TODO list, but it could be September/October. -- Ticket URL: <http://devel.rtems.org/ticket/4923#comment:7> RTEMS Project <http://www.rtems.org/> RTEMS Project
